Impulsive sources are the most commonly used sources. The highest point of a transverse wave is the crest and the lowest point is called a trough. For land seismic sources, it is desirable to generate a highly energetic wave of short duration that is repeatable and does not generate noise that interferes with detection.Mechanical waves in which the particles of matter in the medium vibrate by moving back and forth and perpendicular (at right angles) to the direction the wave travels are called transverse waves.Examples of mechanical compressional/longitudinal waves might include sound waves and some seismic waves.The place on the wave that is pushed together is called the compression and the place that is moving apart is the rarefaction.Mechanical waves in which the particles of matter in the medium vibrate by pushing together and moving apart parallel to the direction in which the wave travels are called compressional or longitudinal waves.Light waves are the only part of the electromagnetic spectrum that is visible to the human eye.Īnother way to classify waves is by how they move:.Are considered e lectromagnetic waves which are waves that can travel through matter or empty space where matter is not present.(Optional) Both primary and secondary waves are. Sound waves, as with all mechanical waves, cannot be transferred or transmitted through empty space (vacuum ). For instance, seismic waves carry energy from the source of the shaking outward in all directions (not in one direction only as the setup shows).For example, water waves, earthquake/seismic waves, sound waves, and the waves that travel down a rope or spring are also mechanical waves.Mechanical waves require the particles of the medium to vibrate in order for energy to be transferred.When there is no medium, certain waves (electromagnetic) can travel through empty spaceĬharacteristics of mechanical and electromagnetic waves:.When waves travel through a medium, the particles of the medium are not carried along with the wave.A medium is a material through which waves can travel.While all waves can transmit energy through a medium, certain waves can also transmit energy through empty space.Waves carry energy through empty space or through a medium without transporting matter. A vibration is a repeated back-and-forth or up-and-down motion.Waves are created when a source of energy (force) causes a vibration.
